The terahertz band of the electromagnetic spectrum was the least explored region of the
spectrum prior to the introduction of the technique known as time-domain spectroscopy …

We review pioneering and recent studies of the conductivity of solid state systems at
terahertz frequencies. A variety of theoretical formalisms that describe the terahertz …

Two-dimensional covalent organic frameworks (2D COFs) represent a family of crystalline
porous polymers with a long-range order and well-defined open nanochannels that hold …

Six years after their birth, terahertz quantum-cascade lasers can now deliver milliwatts or
more of continuous-wave coherent radiation throughout the terahertz range—the spectral …

Surface plasmons have found a broad range of applications in photonic devices at visible
and near-infrared wavelengths. In contrast, longer-wavelength surface electromagnetic …

Gallium nitride (GaN) is one of the most technologically important semiconductors and a
fundamental component in many optoelectronic and power devices. Low-resistivity GaN …

Surface plasmon polaritons and their localized counterparts, surface plasmons, are widely
used at visible and near-infrared (near-IR) frequencies to confine, enhance, and manipulate …

The interaction of high-power lasers with matter can generate Terahertz radiations that
efficiently contribute to THz Time-Domain Spectroscopy and also would replace X-rays in …

Spectroscopies using terahertz (THz) radiation excited by ultrashort laser pulses have been
rapidly developing recently. In this paper, the principles of various types of THz time domain …

Evidence shows that charge carriers in organic semiconductors self-localize because of
dynamic disorder. Nevertheless, some organic semiconductors feature reduced mobility at …
